WAVE POWER GENERATOR.

Specification of Letters Patent. Patented Mar. 14:, 1911.

Application filed June 6, 1910. Serial No. 565,388.

To all whom it may concern;

Be it known that I, Ronnn'r MAX MOBIUS,

. a citizen of Canada, residing at San Diego,

. make and use the same.

This invention relates to a wave power generator and has for its object the provision of an improved form of apparatus adapted to develop power from the motion of the waves or surf.

It is more particularly a device in which the reciprocatingmotion of a buoyant member operating on an inclined frame, istransformed. into mechanical power by means of a' double rack and pinion and a ratchet wheel and heavy balance wheel mounted on a power shaft.

These objects are attained by the form of invention disclosed in this specification. and defined in the claims. I

In the accompanying drawings in which similar characters of reference designate corresponding parts, Figure 1- is a per spective view of the device. Fig. 2 is a detail View of the rack and pinion. Fig. 3 is' a detail view of the float or buoyant member which is actuated by the waves or surf. Fig. 4 is a perspective view of a float or barge on which the power generator may be mounted and thereby made a portable de v1ce.

Referring more particularly to the draw-.

ings, numerals 1, 2, 3, and 4, designate piling carrying heavy timbers 5 and 6, on which are mounted bearings 7, with a power shaft 8, journaled therein. Ratchet pinion 9, smooth pulley 10, and a heavy balance wheel 11 are mounted on the power shaft. Smooth ratchet pawls 12, held in-engagement'with the smooth pulleyby s rings 13, are mounted on pinion 9. The rate et pawls are set to bind and grip the smooth pulley when rotated in the proper direction, thus imparting motion to the power shaft.

A platform 14, securely anchored to the earth, has a frame pivoted thereto in bearings 15. Side bars 16 and 17, of the frame are mounted in an inclined position, being adjustable with parallel horizontal timbers 5 and 6, and having heavy screw bolts 18,

-i fitting a series of threaded holes 19, in said Side bars 16 and 17 are connected bar 20, from which a centrally lotimbers. by cross cated bar '21, extends to and is pivoted to platform 14. Upon thesejnclined bars, a reciprocating float 22, is mounted, consisting of a hollow buoyant'portion having suitably positioned impact surfaces and a' flaring rectangular cup-shaped extension 23, thereon. Pulleys-24, 25, and 26 hold the float in engagement with the sidebars, and double-flanged'pulley 27, perating on bar 21, also supports the float.

A rotary shaft 28 carrying ratchet pulleyv 29 and belt pulley 30,-is mounted on the adjustable frame. A double rack 3,1,having upper and lower members 32 and 33, ar ranged in a vertical plane, is connected to float 22, and is operated thereby, Members 32 and 33, are provided with teeth 3% and 35, respectively pointed in opposite dii'e c tions, and engaging with teeth 36, ofratchetpinion 29, thereby rotating. the pinion in the same direction with both movements of the rack. Teeth 36, are slidably mounted in sockets in the face of the pinion, and

are normally held in operative position by springs 37. The movement of the rack members in the opposite direction from that of the adjacent teeth of pinion 29, will depress the teeth, thus allowing the member moving in the same direction as the teeth, to drive the pinion. A belt '38, connects pulley 29, and ratchet pinion 9.

" In operation, the float is raised upward on the inclined frame and falls again after the wave has passed onward. The movement of the float causes a reciprocating movement of the double rack, which operates the pinion and shaft mounted at the top of the frame. The motion of the Shaft thus driven is transmitted to the power shaft which, by means of its heavy balance wheel' maintains a continuous movement.

In thisdevice both the lifting powerand the power in the horizontal movement of the and uniform rotary waves or surf, are utilized in the generation of-power, and the frame may be adjusted at such angle as to receive and transmit the greatest efl'ective power possible with this device.

The device as herein illustrated andlde scribed, constitutes a single unit or -power generator, and the apparatus may be in-- stalled with a series 0 such units, having adjacent power shafts connected. This mechanism may be installed'upon afloating barge, as a portable device, adapt ing thepqwer generator for use on term 0- rary work, orit may be constructed on so id foundations.

While the means herein provided are well adapted to serve the purposes for which they are intended it is to be understood that the invention is not limited to the precise.

- rocatin float, a tween tie said slde bars, serving as-a support for the float, guide wheels engaging ing the reciprocating motion of the float into a continuous uniform rotary motion.

2. A wave power generator comprising an inclined frame pivoted to a securely anchored' platform, means for adjusting the inclination of the frame, parallel side bars of the frame serving as guides for a recipparallel barback of and bethe side bars, a double flanged uide wheel engaging the supporting bar, a oat carried by the guide wheels, a double rack with its members, arranged in avert-ical plane, a

pinion with ratchet teeth cooperatlngwith .said rack, a rotatory shaft carrying a belt pulley operated by the ratchet pinion, in combination with a ratchet pulley mounted on a power shaft, and abelt transmission between the ratchet ulley .of the power shaft and the belt pu ley operated by the ratchet pinion.

In testimony whereof, I aflix my signature, in presence of two witnesses. ROBERT MAX MOBIUS.
